Fionn Dunne, Nik Petrinic ... 258 pages - Publisher: Oxford University Press; 1st edition (August, 2005) ... Language: English - ISBN-10: 0198568266 - ISBN-13: 978-0198568261 ...

This book gives an introduction to computational plasticity and includes the kinematics of large deformations, together with relevant continuum mechanics. Central to the book is its focus on computational plasticity, and we cover an introduction to the finite element method which includes both quasi-static and dynamic problems. We then go on to describe explicit and implicit implementations of plasticity models in to finite element software. Throughout the book, we describe the general, multiaxial form of the theory but uniquely, wherever possible, reduce the equations to their simplest, uniaxial form to develop understanding of the general theory and we hope physical insight. We provide several examples of implicit and explicit implementations of von Mises time-independent and visco-plasticity in to the commercial code ABAQUS (including the fortran coding), which should prove invaluable to research students and practicing engineers developing ABAQUS 'UMATs'. The book bridges the gap between undergraduate material on plasticity and existing advanced texts on nonlinear computational mechanics, which makes it ideal for students and practicing engineers alike. It introduces a range of engineering applications, including superplasticity, porous plasticity, cyclic plasticity and thermo-mechanical fatigue, to emphasize the subject's relevance and importance.

The aim of Plasticity Theory is to provide a comprehensive introduction to the contemporary state of knowledge in basic plasticity theory and to its applications. It treats several areas not commonly found between the covers of a single book: the physics of plasticity, constitutive theory, dynamic plasticity, large-deformation plasticity, and numerical methods, in addition to a representative survey of problems treated by classical methods, such as elastic-plastic problems, plane plastic flow, and limit analysis; the problem discussed come from areas of interest to mechanical, structural, and geotechnical engineers, metallurgists and others. The necessary mathematics and basic mechanics and thermodynamics are covered in an introductory chapter, making the book a self-contained text suitable for advanced undergraduates and graduate students, as well as a reference for practitioners of solid mechanics.

The present book provides a new method to estimate elastic-plastic strains via a series of linear elastic analyses. For a life prediction of structures subjected to variable loads, frequently encountered in mechanical and civil engineering, the cyclically accumulated deformation and the elastic plastic strain ranges are required. The Simplified Theory of Plastic Zones (STPZ) is a direct method which provides the estimates of these and all other mechanical quantities in the state of elastic and plastic shakedown. The STPZ is described in detail, with emphasis on the fact that not only scientists but engineers working in applied fields and advanced students are able to get an idea of the possibilities and limitations of the STPZ. Numerous illustrations and examples are provided to support the reader's understanding.

Applied Elasticity and Plasticity is a comprehensive work that introduces graduate students and professionals in civil, mechanical, aeronautical and metallurgical engineering to the basic theories of elasticity, plasticity and their practical applications. Based on experimental data of static tension tests of material, several elastic and plastic stress-strain relations are derived, and commonly-used yield criteria and strain hardening rules are discussed as well. Analysis of conventional, deviatoric and mathematical stress and strain in two and three dimensions is presented. Analytical applications include torsion and bending of structural components subjected to various loadings, thick-walled cylindrical and spherical vessels subjected to internal and external pressures, stress-concentrations around holes, stress-intensity factors in structural components containing circular, elliptical and many more concepts important for professionals and students alike.

This book is the first to cover the engineering aspects of severe plastic deformation (SPD) technology used to refine grain structure in metallic materials. The fundamentals of both the well-known and novel SPD processes are explained and the engineering know-how required for successful implementation of these processes revealed. The principles of each SPD technique are explained and insight provided into the mechanics of material deformation and microstructural changes. The equipment used for SPD processing is described including machines and tools.

The book covers the most popular SPD process of equal channel angular pressing, ECAP and its incremental version, I-ECAP. A separate chapter is devoted to tooling used in ECAP/I-ECAP. Another popular SPD process is high pressure torsion (HPT), which produces very good results in terms of refining grain structure but faces some technical challenges. A less known SPD process is cyclic extrusion compression (CEC), which is thoroughly explained as is twist extrusion (TE) which is a relatively new process that is showing good potential. Finally, an original SPD process of accumulated roll bonding (ARB), capable of refining grain structure in sheets, is discussed. The book is intended for students and researchers working in the field of refining grain structure of metals by SPD. By explaining the engineering aspects of SPD, it enables the best SPD process to be chosen for a given application thus avoiding time-consuming and wasteful trials. It also encourages metal forming researchers and material scientists to work together in order to improve existing and develop new SPD processes. Finally, this book is also for industrial engineers, who will ultimately be using the SPD technology for mass production of metals with refined grain structure and improved properties.

"The plastic theory of structures," the author writes, "is an essential complement to elastic theory. The readily applied forms of either theory depend on idealized mathematical models both of the material properties and of the fabricated nature of the structure. By applying each theory in turn to the same structure, a much better overall picture is obtained of the stability, rigidity, and strength than is possible by applying either theory on its own."

Plastic theory is used as the basis of design for the majority of single-story rigid frames and is being increasingly applied to multistory frames. An important feature of the theory is the extent to which intuitive ideas of structural behavior may be used to solve problems. In this text, Professor Horne employs this method to explain the principles involved. He backs up the intuitive approach by formal statements and proofs of theorems and explains the methods of plastic analysis. Methods which are of value in design applications and are suited primarily to hand calculations are emphasized, but methods suitable for computer application are also included. Relevant problems are given at the end of each chapter with answers at the end of the book.

The finite element method is a powerful tool even for non-linear materials’ modeling. But commercial solutions are limited and many novel materials do not follow standard constitutive equations on a macroscopic scale. Thus, is it required that new constitutive equations are implemented into the finite element code. However, it is not sufficient to simply implement only the equations but also an appropriate integration algorithm for the constitutive equation must be provided. This book is restricted to one-dimensional plasticity in order to reduce and facilitate the mathematical formalism and theory and to concentrate on the basic ideas of elasto-plastic finite element procedures. A comprehensive set of completely solved problems is designed for the thorough understand of the presented theory. After working with this new book and reviewing the provided solved and supplementary problems, it should be much easier to study and understand the advanced theory and the respective text books.

The only modern, up-to-date introduction to plasticity Despite phenomenal progress in plasticity research over the past fifty years, introductory books on plasticity have changed very little. To meet the need for an up-to-date introduction to the field, Akhtar S. Khan and Sujian Huang have written Continuum Theory of Plasticity--a truly modern text which offers a continuum mechanics approach as well as a lucid presentation of the essential classical contributions. The early chapters give the reader a review of elementary concepts of plasticity, the necessary background material on continuum mechanics, and a discussion of the classical theory of plasticity. Recent developments in the field are then explored in sections on the Mroz Multisurface model, the Dafalias and Popov Two Surface model, the non-linear kinematic hardening model, the endochronic theory of plasticity, and numerous topics in finite deformation plasticity theory and strain space formulation for plastic deformation. Final chapters introduce the fundamentals of the micromechanics of plastic deformation and the analytical coupling between deformation of individual crystals and macroscopic material response of the polycrystal aggregate. For graduate students and researchers in engineering mechanics, mechanical, civil, and aerospace engineering, Continuum Theory of Plasticity offers a modern, comprehensive introduction to the entire subject of plasticity. Uses a continuum mechanics approach to understanding and predicting the behavior of solids under deformation stress and strain. Presents a modern viewpoint of plasticity which covers the traditional topics of stress-strain relationships, loading and unloading behavior and the microscopic phenomena that occur during deformation. Features the latest developments in the field.

Plasticity for Structural Engineers is a practical work that provides engineers and students in structural engineering or structural mechanics with the background needed to make the transition from fundamental theory to computer implementation and engineering practice. It sets out initially to examine the stress-strain behaviors of materials under simple test conditions, goes on to show how these behaviors can be generalized under combined stresses, and finally outlines the finite element implementation of the generalized stress-strain relations for the solution of practical steel and concrete structural problems. Plasticity for Structural Engineers not only offers the reader an understanding of the fundamental principles and theory of plasticity in a form that does not require extensive mathematical experience, but also provides the reader with a compact and convenient summary of the modern development of concrete plasticity and limit analysis in structural engineering.

Comprehensive introduction to finite elastoplasticity, addressing various analytical and numerical analyses & including state-of-the-art theories: Introduction to Finite Elastoplasticity presents introductory explanations that can be readily understood by readers with only a basic knowledge of elastoplasticity, showing physical backgrounds of concepts in detail and derivation processes of almost all equations. The authors address various analytical and numerical finite strain analyses, including new theories developed in recent years, and explain fundamentals including the push-forward and pull-back operations and the Lie derivatives of tensors. As a foundation to finite strain theory, the authors begin by addressing the advanced mathematical and physical properties of continuum mechanics. They progress to explain a finite elastoplastic constitutive model, discuss numerical issues on stress computation, implement the numerical algorithms for stress computation into large-deformation finite element analysis and illustrate several numerical examples of boundary-value problems. Programs for the stress computation of finite elastoplastic models explained in this book are included in an appendix, and the code can be downloaded from an accompanying website.

Plasticity and Geomechanics presents a concise introduction to the general subject of plasticity with a particular emphasis on applications in geomechanics. Derived from the authors' own lecture notes, excessive use of mathematical methods is avoided in the main body of the text and where possible, physical interpretations are given for important concepts. This book therefore complements Elasticity and Geomechanics by the same authors and will appeal to graduate students and researchers in the fields of soil mechanics, geotechnical engineering, and geomechanics.

Explores the Principles of Plasticity: Most undergraduate programs lack an undergraduate plasticity theory course, and many graduate programs in design and manufacturing lack a course on plasticity―leaving a number of engineering students without adequate information on the subject. Emphasizing stresses generated in the material and its effect, Plasticity: Fundamentals and Applications effectively addresses this need. This book fills a void by introducing the basic fundamentals of solid mechanics of deformable bodies. It provides a thorough understanding of plasticity theory, introduces the concepts of plasticity, and discusses relevant applications. Studies the Effects of Forces and Motions on Solids: The authors make a point of highlighting the importance of plastic deformation, and also discuss the concepts of elasticity (for a clear understanding of plasticity, the elasticity theory must also be understood). In addition, they present information on updated Lagrangian and Eulerian formulations for the modeling of metal forming and machining. Topics covered include: Stress + Strain + Constitutive relations + Fracture + Anisotropy + Contact problems. Plasticity: Fundamentals and Applications enables students to understand the basic fundamentals of plasticity theory, effectively use commercial finite-element (FE) software, and eventually develop their own code. It also provides suitable reference material for mechanical/civil/aerospace engineers, material processing engineers, applied mechanics researchers, mathematicians, and other industry professionals.
